Description

FLUORESCENT ENGLISH FLUORITERogerley Mine, Weardle, Co. Durham, UK
The famous Rogerley Mine in northern England is the only mine in
that country worked exclusively for mineral specimens. It was
discovered in the 1970's in an abandoned limestone quarry and,
following a period of inactivity, reopened in 1999 when new
excavations found more and more spectacular cavities lined with the
location's characteristic fluorite. The present specimen is a good
example, coated with small translucent cubic crystals indicative of
the mineral's isometric habit. Under artificial indoor lighting
they appear almost colorless, with just a soft hint of violet; this
effect is strikingly enhanced in natural sunlight displaying a
lovely soft purple tint, but it is under long wave ultraviolet
light however that the crystals really spring to life, glowing with
a strong fluorescent purple tinged with deep blue. This fine
collector's specimen measures 5 inches across.
